Silene plant named ‘Sunshine n Daydreams’

ABSTRACT

A new cultivar of  Silene  named ‘Sunshine n Daydreams’ that is characterized by bright golden-yellow foliage and abundant bright pink-red male flowers produced from early summer into fall. ‘Sunshine n Daydreams’ does not produce seed.

Genus and species: Silene dioica.

Variety denomination: ‘Sunshine n Daydreams’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of Silene plant, known botanically as Silene dioica in the family Caryophyllaceae and referred to hereinafter by the cultivar name ‘Sunshine n Daydreams’. Silene dioica, commonly known as Red Campion, is dioecious (male and female flowers are borne on separate plants). The parents of ‘Sunshine n Daydreams’ are an unnamed and unpatented golden-foliaged seedling as male parent and an unnamed and unpatented green-foliaged seedling as female parent. ‘Sunshine n Daydreams’ is an asexually-reproduced selection of a male form of Silene dioica and bears only male flowers as disclosed herein.

The inventor has maintained at his nursery in Newton Abbot, Devon, United Kingdom seed lines of Silene dioica from the early 1990s. Beginning in 1995, the inventor sought to develop superior forms of the species by interplanting male and female seedlings raised in previous generations. The inventor's objective was to develop robust male forms which would produce pollen and not seeds, and therefore be reproducible only by asexual propagation. Such male forms could also be expected to have larger flowers with successive breeding. In addition, the inventor considered that golden foliage would be a desirable characteristic in combination with the bright pink-red flowers of Silene.

In 1995, the inventor identified a weak golden-foliaged male-flowered seedling. The inventor transplanted this weak seedling amongst robust green-foliaged female seedlings. After two generations of seed harvest and resowing, the inventor selected a single seedling, the subject of the present invention.

‘Sunshine n Daydreams’ was first asexually propagated in 2012 by the inventor at the inventor's nursery in Devon, United Kingdom. Asexual propagation was accomplished using basal shoot cuttings. Since that time, under careful observation, successive generations have been determined fixed, stable and uniform.

SUMMARY

The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Silene cultivar ‘Sunshine n Daydreams’. These traits in combination set ‘Sunshine n Daydreams’ apart from all other existing varieties of Silene known to the inventor. ‘Sunshine n Daydreams’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, however, without any variance in genotype.

-   -   1. ‘Sunshine n Daydreams’ exhibits bright golden-yellow foliage.     -   2. ‘Sunshine n Daydreams’ produces abundant bright pink-red male         flowers in spring and early summer and continues to flower         steadily throughout summer and into fall.     -   3. The plant habit of ‘Sunshine n Daydreams’ is a compact         rosette.     -   4. A one year old plant of ‘Sunshine n Daydreams’, grown from a         basal shoot cutting is 25 cm to 30 cm in height and in width.     -   5. A mature plant of ‘Sunshine n Daydreams’ grown outdoors in         good garden soil will remain 30 cm in height foliage mound,         excluding flowers, and may spread to 50 cm to 60 cm in diameter.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Silene variety ‘Sunshine n Daydreams’ showing colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘Sunshine n Daydreams’.

FIG. 1 depicts a two year old plant of ‘Sunshine n Daydreams’ growing outdoors in the inventor's nursery garden in Newton Abbot, Devon, England. This drawing was made from a photograph taken in August and depicts the low spreading habit of ‘Sunshine n Daydreams’, the stable golden foliage in summertime and the profuse bright pink-red flowers.

FIG. 2 depicts a close-up view of the golden foliage and the pink-red flowers of ‘Sunshine n Daydreams’.

The photographs were made using conventional techniques and although flower and foliage color may appear different from actual color due to light reflectance, they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of ‘Sunshine n Daydreams’. Data was collected in Santa Barbara, Calif. from one year old plants grown outdoors in a garden border. Color determinations are made in accordance with the 2007 edition of The Royal Horticultural Society Colour Chart, London, England, except where general color terms of ordinary dictionary significance are used. The growing requirements of ‘Sunshine n Daydreams’ are similar to the species Silene dioica.

COMPARISON KNOWN VARIETY

‘Sunshine n Daydreams’ is markedly more robust than the male parent and differs from the female parent by foliage color. The variety of Silene which the inventor considers most closely resembles ‘Sunshine n Daydreams’ is the inventor's variable seed strain (producing both male and female flowers) known as Silene ‘Winter Cream’. In addition to its variability as a seed strain, the leaves of ‘Winter Cream’ become light then mid green as the season progresses, whereas ‘Sunshine n Daydreams’ continues to produce golden-yellow foliage. 

I claim:
 1. A new and distinct cultivar of Silene plant named ‘Sunshine n Daydreams’ as described and illustrated herein.
